Grails ui-performance plugin not working with CKEditor

Question

I installed Grails ui-performance plugin and made the necessary changes in the code. It didn't seem to work for development, I was getting files which name was ending with "_vnull" so I disabled it for development and tried to test with a WAR file. However, when generating the WAR file I get the following error and exception:

[ERROR] 1:0:Compilation produced 55 syntax errors. in lineSource: null sourceName: null

ERROR: problem minifying /Users/maricel/.grails/1.3.5/projects/community-services/stage/plugins/ckeditor-3.4.1.1-SNAPSHOT/js/ofm/scripts/languages/ca.js: Compilation produced 55 syntax errors.

Is this some conflict with the CKEditor plugin? Any idea how to fix it?

Thanks for your help!

Answer 1

I fixed this issue by adding an exclusion for the plugins directory:

uiperformance.exclusions = [ 
        "**/plugins/**"
]

As suggested in this nabble post
